General Information

This archive is a sampling of my 100+ publications. Limited help assisting
people with queries on my codes and papers is available only by electronic mail
correspondence. Sorry, but given that this site has 1000's hits/day, I cannot
mail out hardcopies of code or papers.

This is a UNIX system, and all file names are case sensitive. Files that end
in .gz (gzip), .zip (zip), or .exe (DOS) are in binary format. Therefore,
before retrieving these files, be sure your browser is set to handle binary

Note that files that contain a .ps are PostScript files (after expanding as
appropriate, which can result in an expansion by a factor of 10 for some
files); these will require a PostScript viewer or printer. Portable Document

PostScript viewers.

Unmanaged VPS

ingber.com is run on an unmanaged linux virtual private server (VPS)
machine. Lester Ingber is responsible for all software maintenance. This
machine is monitored externally, and in case of a crash, full service
should be restored quickly, i.e., less than an hour.

qPATHTREE and qPATHTREE will provide researchers in several
disciplines, in contexts utilizing path-integrals in many applied physics
contexts, including problems in physics, neuroscience and blockchain
derivatives, with a new fast numerical C-coded algorithm to perform path
integrals of complex-number systems using the standard GCC compiler.

I'm an alumnus of Brooklyn Technical High School (BTHS) class of
1958.

I'm an alumnus of California Institute of Technology
(Caltech) class of 1962 (Physics).

This set of courses includes my course using physics and attentional
approaches to karate which was taught in my dogos, as well as in this
UCSD course, since 1968. My 1976 book just below includes my 1968
"Physics of Karate Techniques" Instructor's thesis for my JKA/AAKF
Instructor's degree, as well as my techniques developed to promote the
learning of attentional skills in parallel with this physics approach to
the learning of traditional physical skills.

This paper describes a methodology and implementation of teaching a
full curriculum of academics, fine arts and physical disciplines, also
tested as described in smni72_learning.pdf,
based in part on a similar methodology I developed for teaching karate,
in turn based on my brain research.

1982 Training Videos

Below are VHS converted tapes of a karate camp with five 1st Dan Black
Belt students in the Summer of 1982, emphasizing sparring exercises which
were eventually published in Elements of Advanced Karate, karate85_book.html
below. To make these files reasonable size they were converted to
320x240. (The files still are quite large at about 200MB each.) The sound
is quite a bit out of sync with the video a lot of the time due to the
device used to capture the VHS recording. The sequence of files below
follows the order of training sessions, each about 1.5 hours, in this
special camp.

As in any person-person combat, important intense events can take place
within what often superficially appears to a non-interacting observer as
a flow of somewhat ordinary movement. It takes some patience to view
several hours of actual classes to see and appreciate crucial moments in
these exercises that reflect the gradual influence of advanced training.

These videos may be viewed as full training sessions from my Drive
archive

Help With Adaptive Simulated Annealing (ASA) Optimization

Optimization is often required for many systems, ranging from simple to
complex descriptions., e.g., to fit models to data. A general class of
optimization algorithms is included under the heading of importance sampling. A
subset of this class is simulated annealing which, if applied correctly, comes
with a mathematical proof that optimal solutions will be found with some
statistical certainty.

Please read the ASA-README.[] file which is provided with the code and
separately online in pdf, gzip'd ps, txt, and html formats. Especially pay
attention to Sections "Use of Documentation for Tuning" and "Simulated
Annealing is NOT Simulated Quenching"

The learning curve for proper use of ASA -- and other general
importance-sampling that are useful for many classes of systems -- is quite
steep, and you may require some help getting started. I can consult/contract
with you to get started or even work with you towards completion of your
optimization/importance-sampling project. See ingber_terms.html for more
information on this choice.

This is an addendum to the NOTES file in the ASA code, giving some code
contributed by users that may be useful to others. I have included my
first Very Fast Simulated Re-annealing (VFSR) code prepared in 1987,
RATFOR vfsr.r and vfsr_com.r code (unsupported), subsequently compiled
into FORTRAN to run on a Lawrence Livermore supercomputer.

Invited paper to a special issue of Control and Cybernetics on
"Simulated Annealing Applied to Combinatorial Optimization." The listing
of other contributors to this special issue is in asa96_vidal_nahorski.txt

Note that this code was also used as described in L. Ingber, "Trading in
Risk Dimensions," in The Handbook of Trading: Strategies for Navigating and
Profiting from Currency, Bond, and Stock Markets, edited by G.N. Gregoriou
(McGraw-Hill, New York, 2010), p. 287-300.

This paper gives relatively non-technical descriptions of ASA and
canonical momenta, and their applications to markets and EEG. The paper
was solicited by AI in Finance prior to cessation of their publication.

A shorter updated paper with this title appears in the Handbook of
Trading: Strategies for Navigating and Profiting from Currency, Bond, and
Stock Markets published by McGraw-Hill (2010). Only the Table of Contents
and the Abstract appear in https://www.ingber.com/markets05_trd.pdf , as
the publisher has requested all previous markets_trd_report.pdf papers be
removed from the internet. (This report is not online and is occasionally
updated. Contact me for more information.)

The 1968 paper nuclear68_forces.pdf above is based on my 1967 Ph.D.
thesis.

Three papers from 1983-1986 calculated a contribution to the binding
energy of nuclear matter induced by nonlinearities of realistic
momentum-dependent nucleon-nucleon interactions, enhancing calculations I
published in the 1960's based on my 1967 Ph.D. thesis (e.g., the 1968
paper nuclear68_forces.pdf above). Those calculations used such
interactions to detail properties of nucleon-nucleon scattering, deuteron
bound state, nuclear matter, and neutron stars.

Papers markets84_statmech.pdf, markets91_interest.pdf and smni91_eeg.pdf contain an Appendix giving a compact
derivation of the path-integral Lagrangian representation equivalent to the
Langevin rate-equation and Fokker-Planck/Schroedinger-type representations for
multivariate systems with nonlinear drifts and diffusions.

This paper describes a methodology and implementation of teaching a
full curriculum of academics, fine arts and physical disciplines, also

PPI is used in the context of developing experimental data for testing
theories of neocortical interactions in an invited paper referenced
below, "Statistical mechanics of neocortical interactions (SMNI): Testing
theories with multiple imaging data" in smni08_tt.pdf below.

This early report considered oscillations in quasi-linearized
Euler-Lagrange equations. The subsequent study in smni09_nonlin_column_eeg.pdf
considers the full nonlinear system and gives more background and
implications of the calculations. The study after that in smni10_multiple_scales.pdf
includes definitive calculations using PATHINT to evolve multivariate
probability distributions of firing states.
